Revolving bin



Patented Feb. 16, 1943 UNITED STATES PATENT OFFICE REVOLVING BIN Philip Rosenberg, New York, N. Y. Application October 13, 1942, Serial No. 461,848

4Claims. (Cl. 211-131) This invention relates to revolving bins of the kind in which bin units are mounted one above another upon a common supporting shaft with capacity for rotation relative to the shaft and to one another.

Bins of this character have commonly been made in the past exclusively of metal. It has recently become desirable because of war conditions to find substitutes for metal, and to devise new structures employing non-metallic materials wherever possible as substitutes for old structures in which metals were freely used.

In my pending application Serial No. 461,847 for Revolving bins, filed concurrently herewith,

I have disclosed and claimed a revolving bin structure in which the principal parts of the bin sections may all be made of non-metallic materials and united to form a sturdy unit through the very sparing use of metals in joining hardware.

The present invention has to do with a revolv ing bin of the type disclosed in my pending application, and more Particularly with means for providing non-metallic outer wall members for the bin compartments and for securing such;

outer wall in place.

While the primary purpose of the present invention is to enable substitute materials to be employed for metals, it is to be understood that the invention is not limited to such use, but that it may be used to advantage in all metallic structures.

In my pending application Serial No. 426,403 filed January 12, 1942, for Bins, sector-like outer walls for revolving bins are. disclosed, each wall being adapted to be thrust downward and fitted upon an upturned flange of the metallic floor member of the bin unit, together with latching means carried by the wall member and adapted to cooperate with the permanent dividers for holding the outer wall member fixedly but removably in place. Since the outer wall member of my prior application was snugly interlocked by a downward thrust with an upturned arcuate flange of the floor member, there was no freedom for the wall member to rock and no freedom for it to move bodily save in an upward direction, and the function of the latching means there employed was primarily to prevent lifting of the wall member vertically.

When the floor member is of non-metallic material and the outer wall member is of non-metallic material as in the present instance, the device of interfitting the wall member with an upturned flange of the floor member by a simple downward thrust is not available. The wall member cannot be interfitted with the floor member in a manner to securely preclude rocking movement, nor to preclude outward sliding movement. The attaching and latching means of my prior application Serial No. 426,403 is not, therefore, practically available to the same extent for use in a structure employing a nonmetallic floor and outer wall members as in a structure employing metallic floor and outer wall members.

The primary object of the present invention is to provide, in combination with non-metallic floor, outer wall, and divider members, a novel means for attaching and latching the outer wall.

member to a permanent divider in such manner that rocking movement and outward sliding movement are prevented by the attaching and latching means themselves.

Other objects and advantages will hereinafter appear.

In the drawing forming part of this specification,

Fig. 1 is a viewin elevation, broken away'intermediate its ends for compactness of illustration, of a revolving bin embodying features of the present invention;

Fig. 2 is a fragmentary sectional view of the upper bin unit of Fig. 1, taken on the section line 22 looking in'the-direction of the arrows;

Fig. 3 is a, fragmentary detail plan view on a larger scale than Figs. 1 and 2;

Fig. 4 is a fragmentary vertical sectional view taken upon the line 44 of Fig. 3, looking inthe direction of the arrows;

Fig. 5 is a fragmentary vertical sectional View taken upon the line 5-5 of Fig. 4 looking in the direction of the arrows;

Fig. 6 is a view similar to Fig. 3, showing one of the outer wall sectors in the course of being attached to the bin unit; and

Fig. 7 is a detail sectional view taken upon the line 1! of Fig. 6, looking in the direction of the arrows.

The revolving bin comprises a base member I which carries a vertical central shaft 2 upon which the several bin sections 3, 3, are mounted with capacity for rotation relative to the slraft and relative to one another. Each bin section 3 comprises a central supporting sleeve 4. A floor member 5 of any suitable non-metallic material such as wood, Masonite, etc., is attached directly to the central sleeveas disclosed in my pending application Serial No. 461,847 and is further. connected to and supported from the central sleeve 4 through non-metallic permanent dividers 6, the dividers 6 being connected to the sleeve through brackets I and to the outer margins of the floor member through brackets 8. Each bracket 8 is provided at the outer lower corner of the permanent divider 6, to which it is attached. A rivet 9 passed through the bracket 8 and the divider 6 has impaled upon it a washer I and a spacer sleeve II at one side of theldivider 6, and a washer- I2 andta spacer sleeve I3 at the otherside of the divider 6. The spacer sleeves I I and I3 bear against the bracket 8 and against the associated washers, and. the rivet 9 holds the assembly firmly and immovably clamped together.

As illustrated, five permanent ,dividers =6 are provided, and an outer wall sector I4 of nonmetallic material is provided, of properflength to' extend from one permanent divider to .another.

The wall sector I4 is curved to conform substantially to :the :peripherycof ithe ifloor :member :5 ,Fand. is .formed with a. groove I;5":.which :receives xthe outer'smargin:ofthe floor:member 5,;fits it snugly,.iand supports .it. .The wall 'member I4 .is

thereof.

When it is desired to remove the wall member I4, the latches 22 at opposite ends of the wall member are simply swung upward to a position like that marked 22a in Fig. 4, whereupon the wall member I4 can be detached and withdrawn by a movement which is substantially the re verse of that by which it was put in place.

The outer wall member I4 is desirably formed with a card holding groove 24 in the outer face The groove 24 is formed with overhanging marginal portions, being illustrated herein as a dovetail groove. The base of the groove is not flat, but is made convex, as shown at 25, for supporting an inserted card in a convex condition.

I have described what I believe to be the best embodiment of my invention. I do not wish, however, to be .confined to the embodiment shown, but what I desire to cover by Letters Patent is set forth in the appended claims.
